Great guy, okay sex

So I recently started to talk to someone I’ve known for years.

Super sweet, healthy, and understanding guy. Basically hits every mark, but sex.

I will admit he’s a little small but he did say he was kinda inexperienced. My question is how do other women deal with this? Is it a deal breaker? Do you really not think about it or focus on it? Has anyone ever been with a guy and eventually it gets better?
